Description

Technical Field

[0001] This invention relates to the field of wheat drip irrigation, and more particularly to an intelligent adjustable drip irrigation system for wheat cultivation. Background Technology

[0002] In wheat cultivation, drip irrigation pipes buried underground are used for irrigation. This method utilizes the slow seepage of water through the drip irrigation pipes and the capillary action of the soil to evenly deliver water to the roots, significantly reducing surface water evaporation and deep seepage. For crops with well-developed root systems such as wheat, underground irrigation can provide a stable and balanced water supply, significantly reducing surface evaporation and deep seepage, improving water use efficiency, promoting deep root development and plant water potential balance. Because water directly enters the root layer, it helps the plant maintain water balance, reduces the impact of water stress, and effectively supports transpiration during the vigorous growth period. This not only helps maintain dry surface, inhibits weed germination, and reduces the use of herbicides, but also reduces the impact of high temperature or wind speed on evaporation by reducing soil surface temperature fluctuations, thereby improving wheat yield and grain quality.

[0003] However, because the pipelines are buried underground, this irrigation technology cannot directly act on the surface soil, making it difficult to quickly moisten the surface soil. For winter wheat and other crops that need surface water to soften the soil and promote seed germination during the seedling or early emergence stages, this "dry surface, moist root layer" irrigation mode may limit the uniformity of emergence, and even, under extreme drought conditions, cause the surface to lack the necessary moisture protection, affecting the early development of crops. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of existing underground drip irrigation systems, which cannot directly moisten the surface soil and are therefore detrimental to wheat seed germination and early growth, and provides an intelligent adjustable drip irrigation system for wheat planting.

[0005] The technical implementation scheme of the present invention is as follows: an intelligent adjustable drip irrigation system for wheat planting, comprising an infusion pipe, a support plate, a buried pipe, and an upper spray pipe; the infusion pipe has a first channel and a second channel sequentially formed inside; a plurality of support plates are provided at the bottom of the infusion pipe; a diversion channel is formed inside the support plate; a first inlet nozzle is provided on the support plate to connect to the corresponding diversion channel, and the first inlet nozzle is inserted into the first channel of the infusion pipe; a buried pipe is fixedly connected to the front and rear sides of the support plate; each buried pipe has an inlet hole to connect to the corresponding diversion channel in the support plate; the buried pipe has a drip irrigation hole to connect to the corresponding inlet hole; an upper spray pipe is fixedly connected to the support plate; a drainage channel is formed inside the upper spray pipe; a second inlet nozzle is provided on the upper spray pipe to connect to the corresponding drainage channel, and the second inlet nozzle is inserted into the second channel of the infusion pipe; a humidity detection module for detecting soil moisture is installed on multiple support plates; the humidity detection module includes a humidity sensing module, a power storage module, and a signal transceiver module.

[0006] Preferably, the support plate is provided with a positioning plate; the bottom of the infusion tube is provided with a positioning slot that is compatible with the corresponding positioning plate, and the positioning plate is inserted into the corresponding positioning slot.

[0007] Preferably, the support plate is provided with at least one limiting side plate on the front and rear sides to clamp the infusion tube.

[0008] Preferably, a limiting insert plate is provided on the limiting side plate; a limiting insertion hole adapted to the corresponding limiting insert plate is opened on the infusion tube, and the limiting insert plate is inserted into the corresponding limiting insertion hole.

[0009] Preferably, a water mist nozzle connected to the outlet end of the flow channel is fixedly attached to the upper spray pipe.

[0010] Preferably, a number of rubber plugs are fixedly attached to the support plate; hollow channels are opened inside the rubber plugs to connect to the corresponding diversion channels; the middle part of the rubber plug is provided with a concave structure that contracts and squeezes towards the hollow channel, and the middle part of the hollow channel of the rubber plug is initially blocked by the concave structure.

[0011] Preferably, an isolation gasket is fixed to the buried pipe and surrounds the outside of the corresponding drip irrigation hole.

[0012] Preferably, several side rods are fixedly connected to the buried pipe.

[0013] Preferably, an arc-shaped insert is fixedly connected to the support plate.

[0014] Preferably, the arc-shaped insert is fixed with insert teeth.

[0015] Compared with existing technologies, the present invention has the following advantages: The intelligent adjustable drip irrigation system for wheat cultivation of the present invention mainly consists of a delivery pipe, a support plate, a buried insertion pipe, an upper spray pipe, and a rubber stopper. The delivery pipe has a first channel and a second channel. The delivery pipe irrigates the wheat throughout its entire growth cycle through the buried insertion pipe located below ground via the first channel. During the wheat seed germination period, the delivery pipe increases the flow rate of liquid delivered to the first channel in arid environments. Combined with the rubber stopper, this allows for simultaneous underground and surface drip irrigation, promoting wheat seed germination, improving early growth, and enhancing the overall growth of the wheat. In the early stages of growth, the infusion pipe periodically sprays water mist into the surrounding air through the second channel and the upper spray pipe above the ground to simulate rainfall. Combined with the buried pipe and rubber stopper, it provides all-round irrigation, which not only meets the water needs of wheat roots, but also regulates leaf temperature and air humidity. By intelligently adjusting the above three irrigation methods, it ensures normal growth and development of wheat while ensuring water conservation. It overcomes the technical problem that the water flow of buried drip irrigation pipes cannot directly act on the surface soil, which is not conducive to wheat seed germination and early growth and development, and improves the environmental conditions of wheat throughout its entire growth cycle.

[0026] like Figure 3 and Figure 6As shown, each support plate 2 is provided with two positioning plates 203 on the left and right sides; the bottom of the infusion tube 1 is provided with a positioning slot 103 that is adapted to the corresponding positioning plate 203. The positioning slot 103 does not penetrate the infusion tube 1 inward, and the positioning plate 203 is initially inserted into the corresponding positioning slot 103; the bottom of the infusion tube 1 is fixedly connected to the positioning plate 203 of the support plate 2 through the positioning slot 103; each support plate 2 is provided with two limiting side plates on the front and rear sides. 204, and the limiting side plate 204 is in close contact with the outer surface of the infusion tube 1; each limiting side plate 204 is provided with a limiting insert plate 205; the infusion tube 1 is provided with a limiting insertion hole 104 adapted to the corresponding limiting insert plate 205, the limiting insertion hole 104 does not penetrate the infusion tube 1 inward, and the limiting insert plate 205 is initially inserted into the corresponding limiting insertion hole 104; the support plate 2 provides an anti-displacement limiting and fixing connection for the infusion tube 1 through the limiting side plate 204 and the limiting insert plate 205.

[0027] A smart drip irrigation system for wheat cultivation mainly consists of an infusion pipe 1, a support plate 2, a buried pipe 3, an upper spray pipe 4, and a rubber stopper 5. The support plate 2 is placed on the ground, and the buried pipe 3 on the support plate 2 is buried in the soil below the ground. The infusion pipe 1 is laid between all the support plates 2 on the ground. The upper spray pipe 4 and the rubber stopper 5 are both exposed above the ground. The water mist nozzle 41 of the upper spray pipe 4 is installed at a height much higher than the position of the rubber stopper 5. The first water supply device and the second water supply device connected to the first channel 101 and the second channel 102, respectively, are also connected to the management terminal through a signal transceiver module. The management personnel send corresponding control commands to the first water supply device and the second water supply device through the management terminal they carry. The humidity detection module 6 can periodically detect the soil humidity environment. The humidity detection module 6 sends the soil humidity environment data to the management terminal through the signal transceiver module so that the management personnel can intuitively judge whether the soil is dry.

[0028] Throughout the wheat's growth cycle, the external first water supply device continuously delivers water to the first channel 101 of the infusion pipe 1. The water flows through each first infusion nozzle 202 into the corresponding diversion channel 201, then flows through the infusion hole 301 of the buried pipe 3, and finally drips out from the drip irrigation hole 302 into the surrounding soil, thus achieving continuous drip irrigation for the wheat roots.

[0029] During the wheat seed germination period, the first intelligent drip irrigation mode is implemented. When the humidity detection module 6 detects that the soil is in a dry state, which is not conducive to the germination and growth of wheat seeds, the management terminal intelligently sends an enhanced signal to the first external water supply device. The first external water supply device increases the flow rate of water delivered to the first channel 101 of the infusion pipe 1. The water flows through the diversion channel 201 of the support plate 2 under high pressure. At this time, the high-pressure water flows through the hollow channel 501 and opens the central concave structure of the rubber stopper 5 to the surrounding area, allowing the water to flow smoothly through the hollow channel 501 to drip onto the soil, keeping the surface soil moist. This achieves simultaneous underground drip irrigation and surface drip irrigation, promotes wheat seed germination, and improves early growth.

[0030] In the early stages of wheat growth, the second intelligent drip irrigation mode is implemented. When the humidity detection module 6 detects that the soil is in a state of long-term drought, the wheat leaves are at risk of dehydration. At this time, the management terminal intelligently sends a start signal to the external second water supply device. The external second water supply device continuously delivers water to the second channel 102 of the liquid supply pipe 1. The water flows through the second liquid inlet 402 and through the drainage channel 401 of the upper spray pipe 4. The water then passes through the water mist nozzle 41 and is sprayed upward into the outside air environment in the form of water mist. The sprayed water mist gradually covers the wheat leaves to simulate precipitation. At the same time, the drip irrigation with the buried pipe 3 and rubber stopper 5 provides all-round irrigation between the wheat and the planting soil. It can not only meet the water needs of the wheat roots, but also regulate the leaf temperature and air humidity, and improve the environmental conditions of the wheat throughout the entire growth cycle.

[0031] Example 2, as Figures 1-7 As shown, based on the above embodiment 1, each buried insertion pipe 3 in this embodiment is fixed with two isolation gaskets 31, one on the left and one on the right, respectively surrounding the outside of the corresponding drip irrigation through-hole 302; each buried insertion pipe 3 is fixed with several side insertion rods 32, and all the side insertion rods 32 surround the outside of the two drip irrigation through-holes 302 on the same buried insertion pipe 3; after the buried insertion pipe 3 is buried in the soil below the ground, the buried insertion pipe 3 drips liquid to the surrounding soil through the drip irrigation through-hole 302 for a long time. The wheat roots near the buried insertion pipe 3 will gradually grow towards the drip irrigation through-hole 302. The side rod 32 wrapped around the outside of the drip irrigation hole 302 can block the growth of wheat roots, preventing wheat roots from wrapping around the buried pipe 3 and blocking the drip irrigation hole 302. Even if wheat roots come into contact with the outside of the drip irrigation hole 302 of the buried pipe 3, the isolation gasket 31 on the outside of the drip irrigation hole 302 can isolate the wheat roots, creating a gap between the wheat roots and the drip irrigation hole 302. This ensures that water can pass through the gap and flow smoothly out of the drip irrigation hole 302 into the soil, preventing the drip irrigation hole 302 from being blocked by the continuously growing wheat roots.

[0032] Example 3, as Figures 1-7 As shown, based on the above embodiment 1, each support plate 2 in this embodiment is fixed with two front and rear arc-shaped inserts 7, and the arc-shaped inserts 7 are sleeved on the corresponding buried pipe 3; each arc-shaped insert 7 has several insert teeth 71 fixed at its bottom; when the management personnel need to lay the infusion tube 1 and the support plate 2, the infusion tube 1 and the support plate 2 are initially separated, the infusion tube 1 is coiled and externally connected to the pipe reel, and the support plate 2 is stored in the external storage box. During the laying of the infusion tube 1 and the support plate 2, one management personnel only needs to walk and release the infusion tube 1 from the pipe reel. The released part of the infusion tube 1 naturally falls close to the ground. The other management personnel follow and take out the support plate 2 from the storage box in turn, and clamp it in the corresponding position at the bottom of the infusion tube 1. After clamping, the support plate 2 is released. The infusion tube 1 is released, causing the pre-installed support plate 2 to naturally fall to the vicinity of the ground until the buried tube 3 and the arc-shaped insert 7 on the support plate 2 contact the ground. At this time, the arc-shaped insert 7 will work with the buried tube 3 to support the support plate 2. The arc-shaped insert 7 provides anti-tipping support for the buried tube 3, keeping the buried tube 3 in a vertical position. This allows the management personnel to lower the support plate 2 on the infusion tube 1 to the ground without frequently bending over, and ensure that the buried tube 3 remains vertical. Then, the management personnel step on the support plate 2, which pushes the buried tube 3 and the arc-shaped insert 7 down into the soil below the ground. This allows the management personnel to easily insert the buried tube 3 into the soil without bending over. The arc-shaped insert 7 is firmly fixed in the soil by the insert teeth 71, thus quickly completing the laying of the system.
